Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, specifically to a spraying device for automotive parts. Background Technology

[0002] In the automotive manufacturing industry, it is generally necessary to spray paint the surface of the parts after they have been processed. Automotive parts spraying is a systematic process involving multiple stages such as pretreatment, spraying, curing and post-treatment. Its core purpose is to improve the corrosion resistance, appearance quality and mechanical properties of the parts, thereby extending the service life of the car and enhancing its aesthetics.

[0003] However, when existing spraying equipment is used to spray the surface of plate-shaped automotive parts, workers usually have to manually spray the surface of each part one by one. It is difficult to spray multiple plate-shaped parts continuously, which is time-consuming, labor-intensive, and cumbersome, and can easily affect the spraying efficiency of plate-shaped parts. Utility Model Content

[0004] The purpose of this utility model is to provide a spraying device for automotive parts. Through the structural design of the upper clamping member and the lower clamping member, multiple plate-shaped parts can be stably fixed and clamped, solving the problem of difficulty in continuously spraying multiple plate-shaped parts.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a spraying device for automotive parts, comprising a frame on which a rotating wheel is rotatably mounted. Five clamping assemblies are mounted on the rotating wheel, each clamping assembly including an upper clamping member and a lower clamping member. The upper clamping member includes a fixed rod and an upper clamping plate. The top end of the fixed rod is rotatably mounted on the lower surface of the rotating wheel's top end, and a middle plate is provided at the top end of the fixed rod. Two through holes are formed on the middle plate. Two uprights are vertically mounted on the upper clamping plate, and springs are fitted to the outer surfaces of the uprights. The outer surfaces of the top ends of the uprights engage with the through holes. The lower clamping member includes a pneumatic push rod, which is embedded in the upper surface of the rotating wheel's bottom end. The output end of the pneumatic push rod is rotatably mounted on the lower clamping plate.

[0007] Furthermore, two circular grooves are provided on the stand, and bearings are fitted into the grooves. A shaft is installed through the middle of the rotating wheel, and the two ends of the shaft are respectively fitted into the inner rings of the two bearings.

[0008] Furthermore, the top end of the shaft passes through the circular groove to the top of the platform, and a motor is installed on the top surface of the platform, with the output end of the motor connected to the top end of the shaft.

[0009] Furthermore, a mounting base is provided at the bottom of the lower clamping plate, and a bearing 2 is embedded at the bottom of the mounting base. The output end of the lower clamping plate mates with the inner ring of the bearing 2.

[0010] Furthermore, an arc-shaped rack is provided on the stand, and five through slots are opened on the lower surface of the top of the wheel. Bearing three is fitted in the through slots. The outer surface of the top of the fixing rod is fitted with the inner ring of the bearing three. The top of the fixing rod passes through the through slots to the top of the wheel. A gear is fitted on the top of the fixing rod, and the gear meshes with the arc-shaped rack.

[0011] Furthermore, a vertical plate is installed on the stand, and a linear module is embedded in the vertical plate. A pneumatic paint gun is installed in the sliding part of the linear module. Two grooves are opened on the vertical plate, and two sliders are installed on one side of the pneumatic paint gun. The sliders cooperate with the grooves.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, through the structural design of the upper and lower clamping components, uses the output end of a pneumatic push rod to push the lower clamping plate upward, causing the top of the plate-shaped part to be inserted into the arc-shaped positioning groove at the bottom of the upper clamping plate and to compress the upper clamping plate. The spring contraction generates a downward rebound force, which allows the plate-shaped part to be stably clamped between the upper and lower clamping plates. This enables convenient and stable clamping of multiple plate-shaped parts, achieving continuous spraying of multiple plate-shaped parts, shortening the spraying time, reducing operation steps, and improving the spraying efficiency of plate-shaped parts.

[0014] 2. This utility model, through the structural design of an arc-shaped rack, shaft, and fixing rod, uses the meshing of gears and arc-shaped rack to drive the fixing rod to rotate 180 degrees, causing the plate-shaped part fixed between the upper and lower clamping plates to rotate 180 degrees. This allows for automatic rotation of the part, enabling rapid spraying on both sides of the part without the need for manual rotation by workers, reducing worker operation steps, increasing the spraying speed of the part, and ensuring the spraying efficiency of the device.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a spraying device for automotive parts, including a frame 1, on which a rotating wheel 2 is rotatably mounted. Two circular grooves are formed on the frame 1, and bearings are fitted into the grooves. A shaft 201 is inserted through the middle of the rotating wheel 2, with both ends of the shaft 201 engaging with the inner rings of the two bearings, allowing the rotating wheel 2 to rotate on the frame 1. The top of the shaft 201 passes through the circular grooves to the top of the frame 1. A motor 5 is mounted on the top surface of the frame 1. The output end of 5 is connected to the top of the shaft 201, which can provide driving force for the rotation of the wheel 2. The wheel 2 is equipped with five clamping components, including an upper clamping component 3 and a lower clamping component 4. A vertical plate 6 is vertically arranged on the frame 1. A linear module 7 is embedded in the vertical plate 6. A pneumatic paint gun 8 is provided in the sliding part of the linear module 7. Two sliding grooves are opened on the vertical plate 6. Two sliders are provided on one side of the pneumatic paint gun 8. The sliders cooperate with the sliding grooves to realize automatic spraying of parts.

[0025] The upper clamping member 3 includes a fixed rod 301 and an upper clamping plate 302. The top end of the fixed rod 301 is rotatably mounted on the lower surface of the top end of the rotating wheel 2. An intermediate plate 303 is provided at the top end of the fixed rod 301. Two through holes 3031 are opened on the intermediate plate 303. Two uprights 304 are vertically arranged on the upper clamping plate 302. A spring 305 is fitted on the outer surface of the uprights 304. The outer surface of the top end of the uprights 304 is fitted with the through holes 3031.

[0026] The lower clamping component 4 includes a pneumatic push rod 401, which is embedded in the upper surface of the bottom end of the rotating wheel 2. The output end of the pneumatic push rod 401 is rotatably mounted with a lower clamping plate 402. The bottom of the lower clamping plate 402 is provided with a mounting base 4021, and a bearing 2 is embedded in the bottom of the mounting base 4021. The output end of the lower clamping plate 402 cooperates with the inner ring of the bearing 2, which can facilitate the rotation of the plate-shaped parts fixed between the upper clamping plate 302 and the lower clamping plate 402.

[0027] When spraying paint onto a plate-shaped part, the bottom end of the part to be sprayed is placed in the arc-shaped positioning groove on the upper surface of the lower clamping plate 402. The plate-shaped part is then kept vertical and aligned with the arc-shaped positioning groove at the bottom of the upper clamping plate 302. The pneumatic push rod 401 is then activated, causing its output end to push the lower clamping plate 402 upwards. This causes the top end of the plate-shaped part to engage with the arc-shaped positioning groove at the bottom of the upper clamping plate 302, thus compressing the upper clamping plate 302. Under this compressive force, the upper clamping plate 302 pushes the two uprights upwards. 304 slides within the corresponding through hole 3031, causing the spring 305 on the outer surface of the upright 304 to be compressed between the upper clamping plate 302 and the middle plate 303. After being compressed, the spring 305 contracts, generating a downward rebound force, which makes the bottom of the upper clamping plate 302 stably engage with the top of the plate-shaped part, so that the plate-shaped part can be stably fixed and clamped between the upper clamping plate 302 and the lower clamping plate 402. Then, the plate-shaped part is fixed to the other four clamping assemblies on the rotating wheel 2 in sequence according to the above operation.

[0028] An arc-shaped rack 101 is provided on the frame 1. Five through slots are opened on the lower surface of the top of the rotating wheel 2. Bearings 3 fit in the through slots. The outer surface of the top of the fixing rod 301 fits in with the inner ring of the bearing 3, which allows the fixing rod 301 to rotate on the rotating wheel 2. The top of the fixing rod 301 passes through the through slots to the top of the rotating wheel 2. A gear 3011 fits in the top of the fixing rod 301. The gear 3011 meshes with the arc-shaped rack 101. When the gear 3011 rotates to the position of the arc-shaped rack 101, the gear 3011 just meshes with the arc-shaped rack 101.

[0029] In use, the motor 5 on the stand 1 is started, and the output end of the motor 5 drives the shaft 201 to rotate on the stand 1, causing the rotating wheel 2 to rotate on the stand 1. When one of the plate-shaped parts fixed between the upper clamping plate 302 and the lower clamping plate 402 is rotated to be aligned with the atomizing nozzle of the pneumatic paint spray gun 8, the pneumatic paint spray gun 8 is turned on to atomize and spray out the paint. Then, the linear module 7 is started, and the sliding part of the linear module 7 drives the pneumatic paint spray gun 8 to move down slowly and uniformly, so that the pneumatic paint spray gun 8 sprays the aligned plate-shaped part. During the rotation of the rotating wheel 2, when the gear 3011 on one of the upper clamping parts 3 rotates to be aligned with the arc-shaped rack on the stand 1, When 101 engages, the rotation of the rotating wheel 2 causes the gear 3011 to mesh with the arc-shaped rack 101, which in turn drives the fixed rod 301 to rotate on the rotating wheel 2. The torque generated by the rotation drives the part fixed between the upper clamping plate 302 and the lower clamping plate 402 to rotate. The gear 3011 meshes with the arc-shaped rack 101 until the gear 3011 separates from the arc-shaped rack 101. The fixed rod 301 rotates 180 degrees, thereby realizing the 180-degree flip of the plate-shaped part fixed between the upper clamping plate 302 and the lower clamping plate 402. When the flipped part is rotated by the rotating wheel 2 to align with the atomizing nozzle of the pneumatic spray gun 8, the other side of the plate-shaped part can be sprayed.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
